Okay, I admit it, I've been a bit of a snob when it comes to DSLRs for video. It's not that I have said bad things about them, actually I've generally been kind in my praise of them when things are kept in perspective, but I have barely used them myself. In fact, I've had so little interest in shooting with them that when I get on set and have to deal with them, I'm always fumbling with where things are in terms of buttons, menu items, etc. The first still/motion camera to peak my interest is of course the RED EPIC. Small form factor, 5K resolution, low compression, RAW, HDRx, etc., make this the natural progression for someone like me who is used to shooting a RED ONE. And I'm sure that in the not too distant future I'll be shooting with one. However, in the meantime, I've been playing with one of those DSLRs, and I have to say that this has been a liberating experience. The camera is the Panasonic Lumix GH2. Actually, the GH2 is not a DSLR per se, as the design removes the mirror and pentaprism in order to reduce the distance between the lens and sensor. It has an electronic LCD and viewfinder. The sensor is of the Micro Four Thirds variety and a lot of information can be found here if anyone is interested. One of the distinctions of the GH1 and GH2 cameras are their native 16:9 and 3:2 aspect ratio formats rather than crops of the native 4:3 image. They use a bigger sensor matrix that use full diagonal of the image circle in all three formats.
Okay, all tech stuff aside, the thing that has struck me so far, and is probably pretty common knowledge for a lot of people who shoot with these types of cameras is how much freedom one has to walk around and capture images. When I'm out shooting with a RED, it tends to draw a crowd, not so much with this camera. I could stop on a dime, take a shot, and most people just assumed I was taking stills. One woman did notice the LCD and asked if I was shooting video, no big deal.
So, what are my initial impressions. Here are a few.
PICTURE QUALITY
I tend to never analyze video on a computer monitor, as too many things can go wrong there, so I have been playing it on my TV Logic 24" monitor through Premiere CS5.5 as well as FCP. When properly exposed, and using the sweetspot of ISO 160-640, the footage looks really great. If I blow it up or get picky, there is some codec shortcomings, but why bother. If it looks good at 1080P on my monitor, then it will look good on the web. I still need to test skies and other such things to see what kind of banding there could be. In short though, lot of bang for the buck in terms of picture quality. It's not REDCODE and it's not Arri ProRes 444 but it's pretty darn good considering the specs.
LENS MOUNT
The Fotodiox mount I got is a no go for me. Too much play, especially with my zooms, and there seems to be some light leak. Novoflex one arrives today. Hoping that solves the issues. If not I will have to look into having one made.
AUDIO
My Sennheiser G3 wireless is working fine with it. Had to tweak the outputs and dial GH2 to 1 but it works. Biggest issue is no headphone jack. Hooking up a bunch of audio accessories kind of defeats the purpose of a small, stealthy camera, but I'm sure that's the way I'll go if I use this on projects that would warrant a double system sound approach. The stereo mic on top is adequate. I was hoping a SmallHD monitor would solve the headphone problem for me but as I found out, GH2 HDMI does not carry audio.Umm...okay. Time to talk to the nice folks over at Panasonic and point out that allowing audio down that port won't kill sales of AF100. Nor do i think allowing a perfectly clean video signal to come out of the HDMI port will hurt your professional line of video cameras. Pros will go with the proper form factor, professional connections, etc that come with those cameras. If the GH2 is capable of clean output, it should be enabled in firmware. They will steal a large share of the DSLR video market by doing so, which may lead to those shooters choosing their pro line of cameras later on. Seriously, this is a mistake in my opinion. Look how close you are Panasonic. A head phone jack and clean HDMI and you would be off to the races. But, I'm not a bean counter, so I probably don't know what I'm talking about.
FORM FACTOR
It's a very small camera, which I love. It's also not the easiest camera to shoot with and hold still. The first day i shot with it (a workshop on building tiny houses), a lot of my footage is shaky. I was using a Cinevate pistol grip. I wish I had brought my Varizoom stabilizer instead. Lesson learned and now my footage is getting steadier. Last night I was on tripod, so all good there. Keep in mind this is a cheapo tripod from my college days back in the early 90's.
LCD
The brightness and color shifting when going from Live to record are a bit weird. I'm still trying to figure that out. I have a SmallHD monitor coming and will compare the image it sees down the HDMI to the LCD and finally to the image that was recorded and played back on calibrated TV Logic.
WORKFLOW
Pretty easy. Open natively in Premiere CS5.5. Transcode to ProRes in FCP, or transcode to Avid DNxHD. The way the files are named could be a problem though. I need to look into how people are dealing with that. Also, while in the field, get yourself one or two of the NEXTO devices and you'll be good to go. No need for a computer. Or back them up when you get home. I just need to find a really fast SD card reader.
LOW LIGHT PERFORMANCE
I was shooting with Nikon primes that go down to F1.4 or F2.0 and as long as the ambient light was sufficient enough to allow me to keep the ISO at 320 or 640 I was fine. Need to look carefully at the stuff I shot at 1280. It might be okay. In some cases, I set shutter to 30 and dealt with the additional motion blur. Better than changing ISO in some cases. Dynamic range is okay. If I had to take a guess it would be right around 8 stops. I was shooting in Nostalgic mode.
Still a lot to explore with this little camera, but I can say it has me wanting to shoot all of the time, which sometimes isn't the case with big cameras that need support accessories every time you go out. With the GH2, I'm simply a man with a camera and I like that.The next best thing in terms of portability would be a stripped down Epic, as not only is it small, but it packs the biggest punch on the planet in terms of video quality, so that will be the ultimate. But for now, I am happy with this cute little camera.
